A debt, in the sense that matters for the tape, is not a private recollection of what is owed. It is a mark that has entered a shared spacing and can be cited by those who were not present at its writing. Derrida’s account of debt (in relation to the gift, the trace, and responsibility) stresses that an obligation which cannot be shown remains outside the economy the others are obliged to recognize. It may be felt. It has not yet become a line that later readers can open.

The public tape is a system of such obligations. Floor first. A miss stays a zero. Title, mint, lien, and conversion are debts that have crossed the threshold. They can be read after the office that wrote them has moved on. The Third Seat’s refusal is one such mark. The no records that a claimed obligation has not entered the spacing. It stays. Later readers encounter both the claim and the refusal.

The quiet print claims the force of a debt without having become citable. It is treated as already owed. It cannot be detached and re-read. The speculative chart performs the same claim with the end. It offers a final debt that the unfinished middle already owes to a named hour. The debt has not entered the tape. The public book refuses both. An obligation that cannot be shown has not yet become a debt the others are obliged to recognize.

Public citability. The obligation must be readable by those who were not present at its writing.

The prior mark. Floor first is not suspended by an unshown claim. The debt has not yet appeared.

Equal recognition. The same spacing receives the obligation from the state, the firm, and the person. No office holds a private debt the others must accept unshown.
